To evoke a therapeutically effective seizure, electrical stimulation in electroconvulsive therapy (ECT) has to overcome the combined resistivity of scalp, skull and other tissues. Static impedances are measured prior to stimulation using high-frequency electrical alternating pulses, dynamic impedances during passage of the stimulation current. Static impedance can partially be influenced by skin preparation techniques. Earlier studies showed a correlation between dynamic and static impedance in bitemporal and right unilateral ECT.

This study aims at assessing the correlation of dynamic and static impedance with patient characteristics and seizure quality criteria in bifrontal ECT

We performed a cross-sectional single-centre retrospective analysis of ECT treatments at the Psychiatric University Hospital Zurich between May 2012 and March 2020 and used linear mixed-effects regression models in 78 patients with a total of 1757 ECT sessions.

Dynamic and static impedance were strongly correlated. Dynamic impedance was significantly correlated with age and higher in women. Energy set and factors positively (caffeine) and negatively (propofol) affecting seizure at the neuronal level were not associated with dynamic impedance. For secondary outcomes, dynamic impedance was significantly related to Maximum Sustained Power and Average Seizure Energy Index. Other seizure quality criteria showed no significant correlation with dynamic impedance.

Aiming for low static impedance might reduce dynamic impedance, which is correlated with positive seizure quality parameters. Therefore, good skin preparation to achieve low static impedance is recommended.

Previous studies have not investigated response rates after electroconvulsive therapy (ECT) in patients with non-psychotic treatment-resistant depression (TRD).

To assess and compare the response rate of ECT for patients with TRD and non-TRD, in a large and clinically representative patient sample.

Patients aged ≥18 years, who were treated for a unipolar, non-psychotic depressive episode with at least one ECT session as part of a first-time, index ECT series between 1 January 2011 and 31 December 2017 were included from the Swedish National Quality Register for ECT. Patients who had initiated a third consecutive trial of antidepressants or add-on medications before start of ECT were classified as having TRD. Patients not meeting criteria for TRD were classified as non-TRD. The main outcome was response to ECT according to the Clinical Global Impressions – Improvement Scale (CGI-I), scored as 1 or 2 (‘very much’ or ‘much improved’ after ECT, respectively). Logistic regression was used to compare outcome measures between TRD and non-TRD, adjusting for potential confounders.

A total of 4244 patients were included. Of these, 1121 patients had TRD and 3123 patients had non-TRD. The CGI-I response rate was 65.9% in the TRD group compared with 75.9% in the non-TRD group (adjusted odds ratio 0.64, 95% CI 0.54–0.75). Older age and more severe depression were predictors of response in patients with TRD.

A clear majority of patients with TRD, as well as patients with non-TRD, responded to ECT, although the response rate was somewhat lower for TRD.

Electroconvulsive therapy (ECT) is an effective and safe medical procedure that mainly indicated for depression, but is also indicated for patients with other conditions. However, ECT is among the most stigmatized and controversial treatments in medicine. Our objective was to examine social media contents on Twitter related to ECT to identify and evaluate public views on the matter.

We collected Twitter posts in English and Spanish mentioning ECT between January 1, 2019 and October 31, 2020. Identified tweets were subject to a mixed method quantitative–qualitative content and sentiment analysis combining manual and semi-supervised natural language processing machine-learning analyses. Such analyses identified the distribution of tweets, their public interest (retweets and likes per tweet), and sentiment for the observed different categories of Twitter users and contents.

“Healthcare providers” users produced more tweets (25%) than “people with lived experience” and their “relatives” (including family members and close friends or acquaintances) (10% combined), and were the main publishers of “medical” content (mostly related to ECT’s main indications). However, more than half of the total tweets had “joke or trivializing” contents, and such had a higher like and retweet ratio. Among those tweets manifesting personal opinions on ECT, around 75% of them had a negative sentiment.

Mixed method analysis of social media contents on Twitter offers a novel perspective to examine public opinion on ECT, and our results show attitudes more negative than those reflected in studies using surveys and other traditional methods.

Electroconvulsive therapy (ECT) is administered following general anaesthetic induction with methohexital, thiopental, etomidate, alfentanil, remifentanil, propofol or ketamine. One approach for idealizing the induction anaesthesia for ECT is combining two agents (e.g. ketamine-propofol) with synergistic anaesthetic properties and non-additive anticonvulsive and hyperdynamic effects.

To establish any superiority between ketamine-propofol (ketofol) combination and etomidate in terms of seizure characteristics and hemodynamic measures.

We have combined our previous case series (etomidate vs thiopental) with new data regarding propofol and ketofol. ECT stimulus duration, stimulus frequency, the stimulus charge applied, duration of central seizure time, number of stimulation trials, plus anaesthetic used in the individual sessions were retrieved. A total number of 1092 sessions (239 sessions with etomidate, 233 with thiopental, 275 with propofol, and 345 with ketofol induction) were included in the linear mixed-effects model analysis.

Etomidate was superior in terms of seizure duration compared with thiopental. There was no significant difference in seizure durations between ketofol, propofol and thiopental, however, number of failed stimulation trials within a session increased significantly with propofol use compared with etomidate and ketofol. The required amount of charge (stimulation dosage) was significantly lower when ketofol was used, compared with thiopental. Additionally, within the ketofol sessions only the propofol dose significantly increased the amount of required dose.

Etomidate and ketofol displayed certain superiorities in terms of seizure characteristics when used as induction anaesthetics for ECT. Therefore, both etomidate and ketamine used in combination with propofol may be considered to be the gold standards of ECT anaesthesia.

knowledge and atittudes of psychiatric nurses should be continuously evaluated and updated to ensure a quality care in electroconvulsive therapy (ECT) unit.

Assessment of the psychiatric nurses knowledge and attitudes towards ECT.

A cross sectional descriptive study was conducted in multiples psychiatric departments in Razi Hospital Tunisia between January and April 2021.We asked 30 psychiatric nurses using a questionnaire evaluating their knowledge and attitudes towards ECT technique and its impact on the medical care.

Our study revealed a lack of knowledge on ECT among psychiatric nurses.In fact, 93% of nurses reported that schizophrenia represents the most frequent indication. Pregnancy was considered as a contraindication by all participants. ECT was not recognized as a first line treatment and Only few knew the complet medical checkup before ECT.As for their opinion about this technique, 73 % of the nurses have a positive attitude towards ECT and think that it is very effective .

Nurses have a major role in the progress of every ECT-session .For that, specific training can only improve their knowledge and promote more positive attitude toward ECT.

Electroconvulsive therapy (ECT) is a medical treatment for those patients with high suicide risk or refractory psychiatric disorders. It is currently a safe technique, and its effectiveness has been widely demonstrated.

Presentation of a clinical case about a patient with drug-resistant delusional disorder and high suicide risk, who eventually received ECT treatment.

Bibliographic review including the latest articles in Pubmed about ECT procedure, effects and use.

We present a 45-year-old man, who visited different doctors several times by reporting he had the feeling of “having a brain tumor or a vascular disorder”, so he requested imaging tests (computed tomography and magnetic resonance). These tests were absolutely normal, but he kept thinking something was wrong, and eventually attempted suicide by hanging (his family founded him before it was too late). The patient was admitted to hospital, and started psychopharmacological treatment, with minimal response. He desperately insisted that he had “something inside his head”. At this point, it was proposed to start ECT, and the patient accepted. After 6 bilateral ECT sessions, he was visibly more relaxed and less worried, and he no longer presented autolytic ideation. He was still a little bit suspicious about the feeling of having a neurological disease. Currently, the patient runs a follow-up consultation.

Electroconvulsive therapy is a safe and effective technique for those patients with high suicide risk. It may be useful to perform imaging tests in certain cases, for detecting intracranial pressure, acute hemorrhage, tumors… A follow-up of these patients must be performed

Anorexia nervosa has an important burden on both patients and families, with important comorbidities such as depression and obsessive symptoms. These are more resistant to pharmacological treatment than in non-anorexia patients, due to both biological and psychological mechanisms. Electroconvulsive therapy is the best available therapy for treatment resistant depression making it a treatment to consider in treatment resistant depression in anorexia though only case reports exist.

To review the current evidence for electroconvulsive therapy of depression in patients with anorexia nervosa as well as it’s ethical challenges

Non-systematic review of the literature with selection of scientific articles published in the past 10 years; by searching Pubmed and Medscape databases using the combination of MeSH descriptors. The following MeSH terms were used: “electroconvulsive therapy”, “anorexia nervosa”.

Electroconvulsive therapy in anorexia has no controlled trials with mostly case reports available on scientific databases. It presents important challenges due to patient age, medical status and ethical challenges. Even less evidence exist for electroconvulsive therapy in children and adolescents than for adults, anorexia can complicate medical status presenting an anesthetic and life-support challenge and it’s egosyntonicity can place a legal and ethical challenge when patient refuses treatment.

Anorexia has a dramatic burden on patients and families affected, with integrated evidence-based treatment being necessary both for treating the current episode and for remission prevention. Case-reports show that electroconvulsive therapy can play a role on treatment resistant depression in anorexia.

Intelectual disability is an illness with an important burden on patients and caregivers, especially when severe and when comorbidities such as other psychiatric disorders are present. There are case reports of treatment resistant self-aggression, agitation, epilepsy, catatonia and psychosis successfully treated with electroconvulsive therapy although controlled studies were not found.

This work reviewed the current evidence for the use of electroconvulsive therapy in the management of patients with intellectual disability as well as its ethical and methodological implications.

Non-systematic review of the literature with selection of scientific articles published in the past 20 years; by searching Pubmed and Medscape databases using the combination of MeSH descriptors. The following MeSH terms were used: “electroconvulsive therapy”, “intellectual disability”.

Patients with intellectual disability can have incapacitating comorbilities that greatly impair quality of life, and may require withdrawl from the community Treatment often differs from the general population as psychotropic medication can worsen other comorbilities. Electroconvulsive therapy can be a relevant treatment option for comorbidities in this population due to its safety profile. Ethical considerations should be taken into account, especially with non-verbal patients or when adequate representatives have not been chosen or cannot be reached. Different legal challenges may be present on different countries.

Electroconvulsive therapy and intellectual disability share the burdens of heavy stigma and low investment. Intellectual disability and it’s commorbidites present both a diagnostic and treatment challenge. Electroconvulsive therapy is an important weapon capable of restoring patients to their families and diminishing the burdens of caregivers and healthcare systems

Introduction: Residual depressive symptoms are common after a successful acute treatment of late-life depression (LLD), and their presence predicts increased risk of relapse. While electroconvulsive therapy (ECT) is the most effective treatment for LLD, little is known about which particular symptoms remain and impact long-term outcome after a successful acute ECT course.

Objectives: We aimed to assess the association between specific residual depressive symptoms after an effective acute ECT course for LLD and relapse at six-month follow-up.

Methods: In this prospective cohort study, including 110 patients aged 55 years and older with LLD, information about relapse was collected six months after the acute ECT course. Relapse was defined as a Montgomery-Åsberg Depression Rating Scale (MADRS) score >15, hospital admission or restart of ECT. We used multivariable stepwise logistic regression models including the scores on the 10 individual MADRS items at the end of the acute ECT course to predict relapse.

Results: Of the 80 responders with available six-month follow-up data, 29 patients (36.25%) had suffered relapse. Higher scores on the MADRS items ‘reduced sleep’ (odds ratio (OR)=2.03, 95% confidence interval (CI)=1.11-3.69, p=0.0214) and ‘lassitude’ (OR=1.62, 95% CI=1.00-2.62, p=0.0497) at the end of the acute ECT course were significantly associated with increased risk of relapse at six-month follow-up.

Conclusions: Some residual depressive symptoms, including sleep disturbance and fatigue, may help better identify patients vulnerable to relapse following a successful acute ECT course for LLD. Future studies assessing interventions that target specific residual symptoms may further reduce post-ECT depressive relapse.

Kleptomania is characterized by recurrent failure to resist the impulse to steal items of little value despite the ego-dystonic impulse and awareness of the wrongfulness of the act. Its prevalence is considered to be 0.6–0.8% in the general population and it is mostly comorbid with other psychiatric disorders. Kleptomania is a disabling disorder since patients suffer from emotional distress and impaired functioning.

Although there is no cure, treatment may help prevent Kleptomania worsening and its negative consequences. We propose a review of the therapeutic approach to this disease.

Non-systematic literature review.

No effective treatment is available for Kleptomania. Better efficacy can be achieved by combining psychotherapy with pharmacotherapy. Different treatment interventions can be selected based on clinical similarities to other disorders, co-occurring conditions or behavioral core features. Patients with significant mood symptoms may benefit from mood stabilizers or antidepressants. For patients with shoplift cravings and/or family history of substance use disorders, Naltrexone may reduce symptoms. Stimulants may be useful for Kleptomania bassociated with Attention Deficit Hyperactivity Disorder impulsivity. Benzodiazepines are effective in tension relief when used as adjuvants, at the beginning of treatment. Electroconvulsive therapy should be reserved for patients with treatment-resistant symptoms and comorbid depression. Cognitive-behavioral therapy has replaced Psychoanalytic and Psychodynamic psychotherapies.

Treatment helps decrease disruption to the person’s life, preventing the intense shame, legal, social, family, and occupational repercussions of Kleptomania. Although pharmaceutical and psychosocial interventions are available, we still lack specific treatments for Kleptomania.

Despite its good results and tolerability in adults, electroconvulsive therapy (ECT) is barely administered in children and adolescents, with scarce evidence in these patients.

We aim to summarize the data available to give a clearer view of how children and adolescents might benefit from ECT.

We’ve done a bibliographic review in PubMed and Cochrane Library searching for articles that include the terms “electroconvulsive therapy” and “adolescents” and/or “children” and their variations.

Current evidence supports the use of ECT in various indications as mood disorders, schizophrenia spectrum disorders, catatonia, neuroleptic malignant syndrome and self-injurious behaviours associated with autism, Tourette’s syndrome or intellectual disability. The efficacy and safety it’s comparable to adults and there are no absolute contraindications. Side-effect profile it’s also similar to the general population, reporting as the most frequent adverse effects headache, generalized body aching, and nausea or vomiting.

Tranylcypromine (TCP), an irreversible monoamine oxidase inhibitor (MAOI), is recommended for difficult-to-treat depression. Besides the requirement of a low-tyramine diet, there are concerns about the safety of TCP treatment during anaesthesia and electroconvulsive therapy (ECT). For safety reasons, many psychiatrists prefer to terminate TCP before ECT.

To assess the safety of tranylcypromine treatment during ECT series in patients with difficult-to-treat depression (DTD).

In this retrospective study we report on n=19 patients, who were treated with tranylcypromine during the ECT series. ECT parameters, clinical and safety data were obtained from our clinical database.

Mean age of patients was 51 years (range 29-77) at time of the first ECT sessions. 58 % (n=11) of patients were female. In total, 198 ECT sessions were analysed (mean 11, median 9,5 per patient). Mean TCP dose was 44 mg at time of first ECT (median 43). Concomitant TCP and ECT treatments were well tolerated during the entire ECT series. In one case TCP treatment was discontinued due to self-limiting bigeminus during the ECT session. In another case TCP and other drugs as well as the ECT series were stopped after the patient developed delirium. At the end of ECT series the mean TCP dosage was 37 mg.

Tranylcypromine appears to be safe during ECT series and does not necessarily have to be terminated prior to electroconvulsive therapy.

Covid-19 was declared a global pandemic by the WHO on 11 March 2020. From the beginning, the pandemic posed a challenge to the different health systems around the world, which were forced to prioritise and distribute their resources as efficiently as possible. During the period between 11 March 2020 and 28 April 2021, the Regional ECT Unit of the Region of Murcia remained closed.

- Determine the clinical status of patients on maintenance ECT in the Regional ECT Unit during the Covid-19 pandemic.

- Prioritise resumption of treatment in those who were clinically decompensated or at risk

- Understand the consequences of discontinuation of maintenance ECT for these patients.

A longitudinal descriptive study was conducted during the month of May 2020.

Thirty-seven patients were contacted by telephone. On the first call, a total of 15 patients were unstable or at risk of decompensation.

Prior to the second call, CT was administered preferentially to a total of 8 patients and programmed to 2. On the second call, a total of 11 patients were at risk of decompensation.

The closure of the Regional ECT Unit had negative consequences for patients undergoing maintenance treatment. Electroconvulsive therapy is an essential part of the treatment of psychiatric patients both in acute episodes and in relapse prevention.

Cardiovascular events (CVE) are infrequent adverse effects in patients receiving electroconvulsive therapy (ECT). Nonetheless, it constitutes a threat for patient’s life and may compromise continuing ECT.

To describe a case of acute-onset atrial fibrillation under combined therapy with ECT and venlafaxine.

We present a 76-year-old man diagnosed of delusional disorder and without any previous CVE, who was hospitalized in our acute psychiatric unit by major depressive episode with psychotic symptoms resistant to pharmacological treatment (valproic-acid 100mg/d, haloperidol 6mg/d, venlafaxine 300mg/d). ECT was initiated presenting atrial fibrillation after first session of ECT, requiring amiodarone and anticoagulant treatment for stabilization. Second session of ECT was delayed for three-weeks, worsening the psychiatric symptoms. Haloperidol was discontinued initiating lurasidone with better cardiovascular profile.

CVE occur in 2% of the patients receiving ECT, being acute arrhythmia the most frequent one. Among them, few cases of atrial fibrillation (AF) under ECT have been reported. It has been hypothesised that initial vagal response followed by catecholamine surge secondary to ECT could facilitate the development of AF. In addition venlafaxine, an antidepressant drug, may also predispose to arrhythmia in high-risk individuals. High doses of venlafaxine (>300mg/d) combined with ECT have been related with an increment of CVE.

Although clinically effective for the treatment of major depression disorder, combined therapy of ECT and venlafaxine could precipitate the start of a CVE in genetically susceptible individuals. Therefore, identify and clarify potential risk factors other than previous history of CVE is critical to reduce morbidity and mortality in these patients.

Electroconvulsive therapy (ECT) is proposed to exert an effect on white matter (WM) microstructure, but the limited power of previous studies made it difficult to highlight consistent patterns of change in diffusion metrics.

We initiated a multi-site mega-analysis and sought to address whether changes in WM microstructure occur following ECT.

To this end, diffusion tensor imaging (DTI) data (n=58) from 4 different sites were harmonized before pooling them by using ComBat, a batch-effect correction tool that removes inter-site technical variability, preserves inter-site biological variability and maximizes statistical power. Downstream statistical analyses aimed to quantify changes in Fractional anisotropy (FA), Mean Diffusivity (MD), Radial Diffusivity (RD) and Axial Diffusivity (AD), by employing whole-brain, tract-based spatial statistics (TBSS).

ECT increases FA in the right splenium of the corpus callosum and the left cortico-spinal tract. Both the left superior longitudinal fasciculus and the right inferior fronto-occipital fasciculus showed increases in AD. Increases in MD and RD could be observed in overlapping white matter structures of both hemispheres. Finally, responders showed significantly smaller FA values in the left forceps major and smaller AD values in the right uncinate fasciculus compared with non-responders.

This is the first and largest multi-site mega-analysis to demonstrate that ECT normalizes altered WM microstructure in important brain circuits that are implicated in the pathophysiology of depression. Furthermore, responders appear to present a more decreased WM integrity at baseline, which if replicated could serve as a biomarker for ECT response.

The Department of Psychiatry at Semmelweis University is the largest electroconvulsive therapy (ECT) centre in Hungary, where a total number of around 300 treatments are conducted every year. Certain changes were administered in 2018 and 2019 in our logistics and internal protocols that helped to increase the number of treated patients and improve quality of care. The COVID-19 pandemic caused serious disruptions in the Hungarian mental health care system , therefore there was a realistic fear that many patients who required ECT would not receive this form of tretament.

Our goal was to assess the effects of the pandemic on our ECT service, and to analyse whether patients were able to receive treatment, despite the logistical difficulties.

We retrospectively gathered data from our internal documentation to compare the number of ECT treatments with the previous years. We also had to take into account the fluctuation in our general caseload of psychiatric patients, since our Department acted as a COVID-19 treatment centre for several months.

Total number of ECT treatments decreased in 2020 after a peak in 2019, however the numbers were not much lower compared to the years before changes in 2018. Unfortunately, we see a more direct effect of the 3rd wave of the pandemic.

We can conlude that there is a decrease in the number of ECT treatments due to the pandemic, however, the fact that we still provided service in most parts of 2020 and 2021 for patients with the most severe conditions is a serious achivement.
